Chapter 10, Problem 10.18P
A 2-in. (50.8 ram) diameter orifice plate is installed within a 3-in. (76.2 cm) diameter pipe and uses flange taps. The engineer needs to monitor water flow rate through the pipe. She anticipates that water will flow through the pipe at 54 fr/min (1.53 m3/min) and needs to select a pressure transducer. Estimate the pressure drop in bars.

The flow rate through a control valve is 10 gpm. The area of the opening of the valve is 2 in^2 andthe pressure after the valve is 10 psi. What would be the approximate pressure reading at the gaugebefore the valve? Calculate the power loss across the valve?
It is desired to pass water from point 1 to point 3 by means of a hydraulic pump, both tanks are open to the atmosphere, the diameter of the pipe is uniform. The external diameter has a value of 28 mm with a thickness of 2mm. If the friction losses are estimated to be 4N.m/N, it is known that the fluid velocity in the pipe is 3m/s What will be the flow rate flowing through the pipe?
Based on the layout of the water supply system, as show in Figure 1, the pressure, in psi, is estimated be 46 at the faucet in the and floor of the residential
building. Consider flow through the delivery pipe, Q = 1.50 cfs and diameter of the
pipe, D = 2.65 inch with e = 0.015 inch. Ingore the minor pressure losses and use
the following formulae to calculate the major pressure losses. The additional power in hp required to provide the recommended pressure of 58 psi at the building is
nearly. Assume f = 0.0175.
Use g = 62.4 lb/f3 for water. Water temperature is 20°C (68°F).
